stash: allow "stash show" diff output configurable

Some users might want to see diff (patch) output always rather than
diffstat when [s]he runs 'git stash show'.  Although this can be
done with adding -p option, users are too lazy to type extra three
keys.

Add two variables that control to show diffstat and patch output
respectively.  The stash.showStat is for diffstat and default is
true.  The stat.showPatch is for the patch output and default is
false.
